SHIP PROPELLING MECHANISM.

Specification of Letters'Iatent.

Patented Oct. 15, 1918.

Application filed July 13, 1917. Serial No. 180,340.

To all whom it may concern:

Be it known that I, CHARLES J. OLSEN, a citizen of the United States, and a resident of New York, borough of Brooklyn, county of Kings, and State of New York, have invented a certain new and useful Improvement in Ship Propelling Mechanism, of which the following is a full, clear, and ex act specification.

This invention relates to a class of apparatus adapted to be used in conjunction wit marine vessels.

My invention has for its object primarily to provide a mechanism designed to be employed for propelling ships and other marine vessels independently of the use of propellers, and which may be applied to vessels having propeller equipment so as to be used in event of accident occurring to the pro peller as well as being susceptible of employment in conjunction with vessels not supplied with other driving means. The invention consists mainly of one or more cylinders having open corresponding ends, and these cylinders are adapted to be arranged in the hull of a ship so that their open ends lead exteriorly of the hull. In each cylinder is a plunger which is reciprocable inwardly and outwardly of the open ends of the cylinders, and these plungers may be driven by one or more engines of suitable types.

Other objects of the invention are to provide means for imparting reciprocation to the plungers when the engines are driven; to provide one or more gates whereby the open end of each cylinder may be closed when the plunger therein requires repairing, or repacking; and to provide a propelling mech anism which may be made for use on marine vessels of various ty es. v

l/Vith these and 0t or objects in view the invention 'willbe hereinafter more particularly described with reference to the accompanying drawings which form a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and will then be pointed out in the claims at the end of the description.

In the drawings, Figure 1 is a fragmentary view taken through part of the stern portion of the hull of'a ship showing a top plan of one form of propelling mechanism embodying my invention applied thereto.

Fig. 2 is an enlarged detail sectional view, partly fragmentary, taken on the line II-II of Fig. '1. l

' Fig. 3 is a detail sectional view, taken on the line III-J11 of Fig. 2, and

Fig. 4 is a detail sectional view, partly fragmentary, taken on the line IV-IV of Fig. 2.

They mechanism may include one, or a number of cylinders, though two corresponding cylinders 10 and 11 are preferably employed for being applied to a ship, or other marine vessel, as 12, so as to be arranged in spaced parallel relation on similar longitudinal planes in the stern, as 13, of the ship. Each of the cylinders may be made with a chambered body portion 14, a tubular head 15 communicating with the chamber of the body portion, and one end of the tubular head may be interiorly recessed, as at 15*. Adjacent to the body portion of each cylinder opposite to its head is an upwardly ex tending casing 16 preferably of a substan-- tially rectangular shape. Each of the casings is of a length so as to protrude some distance above the chambered body portion 14 of its cylinder, and each casing has an open upper end which is closed by a cap 17. with a threaded opening centrally therethrough. On the casing 16 of each cylinder opposite to its body portion may be, a tube 18 and both tubes are arranged so that one of their corresponding ends lead eXteriorly of the boat through openings provided in its hull.

Through the lower part of the casing 16 of each cylinder are openings 19 and 20 both of which are in register with the passage of the tube of its cylinder-as well as being in register with the passage of its tubular body portion. The cylinders thus are formed with open ends, and reciprocable in the cylinders are plungers 21 and 22. The plungers 21 and 22 may be of shapes conforming with the bores of the cylinders, and these plungers may be of solid metal, or may be made of hollow sheet metal with the ends thereof which are reciprocable inwardly and outwardly of the tubes 18 being closed by a plate 23, while transversely of the second end of each plunger is a bar 24. Both of the plungers are considerably longer than the cylinders as well as being of diameters so that their closed ends will properly take the water at the stern of the boat when reciprocated. Journaled in the wall of the body portion 14: of each of the cylinders 10 and 11 is a shaft 25, and on each shaft interiorly of the chamber of each body portion is a roller 26 rotalably supporting the plunger of its respective cylinder. In spaced relation to the fronts of the heads 15 of the cylinders 10 and 11 are pairs of spaced uprights 27, 27? and 28, 28 of the uprights 27 and 27 is a shaft 29 car; rying a roller 30 arranged between the up rights in rotatable contact with the underside of the plunger 21, and journaled in the upper parts ofthese uprights is a shaft 31 carrying a roller 32 also disposed between the uprights in rotatable contact with the top of the plunger. Journaled in the lower parts of the uprights 28, 28 is a shaft carrying a roller, not shown, arranged between the uprights in rotatable contact with the underside of the plunger 22, and journaled in the upper parts of these uprights is a shaft'35 carrying a roller 36 also disposed between the uprights in rotatable contact with the top of the plunger. By providing these rollers and uprights in this manner the plungers will be properly supported when reciprocated inwardly of the hull of the boat, and to pack each plunger in its cylinder so as to be water-tight in the recess 15 of each cylinder may be a stulhng-box 37, and a gasket 37 of rubber, or other material which surrounds the plunger of the cylinder. In order to drive the plungers 21 and 22 I may employ any desired types of engines, for example, one or a pair 'of combustion engines, as 38 and 39, of any well known, or

preferred makes, and these engines are suitably arranged in the hull of the boat in proximity to the cylinders 10 and 11. When a pair. of engines are used they may be driven in unison as well as being provided with a common drive shaft 40, and serving as means to transmit reciprocation to the plungers when the engines are driven, two spaced standards 41 and 42 are arranged between the engines and the cylinders 10 and 11. In bearings provided on these standards is 'journaled the ends of a shaft 43 at one end of which may be a drive wheel 44, and on the central part of this shaft is a pulley 45 over which is guided a belt 46 which also passes over a pulley 47 provided on the shaft 40 of the engines. Extending from the shaft 43 between the drive wheel 44 and the pulley 45 is a crank 48, and projec ing from this shaft between the pulley 45 and the standard 41 in an opposite direction to the crank 48 is a second crank 49. To the crank 48 is pivoted one end of a crank arm 50 having its other end pivoted to a pronged lug, as 51, projecting from the bar 24 of the plunger 22, and to the crank 49 is pivoted one end of a crank arm 52 having its other end pivoted to a pronged lug 53 protruding from the bar 24 of the plunger 21.

The cranks 48 and 49 together with the arms '50 and52 being arranged in this manner, the plungers 21 and 22 will be alter- J ournaled in the lower parts nately reciprocated when the engines are driven by the power being transmitted from the shaft 40 of the engines to the pulley 47, belt 46 and pulley 45. The shaft 43 will thereby be driven, and in turn the cranks 48 and 49 will be revolubly swung for. con secutively' operating the crank arms 50 and 52 to cause theplungers to likewise reciprocate in their cylinders. As the plunger-s are driven outwardly of the stern of the boat they will take the water alternately for cans ing the boat to be propelled.

F or the purpose of permitting the open end atone or both of the cylinders 10 and tangular shape of a size larger than the diameter of the bore of the cylinder. Projecting in spaced parallel relation from the upper and lower parts of one of the corresponding faces of the plate of each gate are two arms, or bars, as 57 and 58. 56 with these bars of each gate are arranged normally in the upper part of the casing 16 of each of the cylinders so that the face of theplate opposite to its bars are The plate in movable contact with the wall of the cas- 3' ing which adjoins the chambered body portion 14 of the cylinder. The bars 57 and 58 of'each plate are thereby disposed crosswise of their casing, and the bars together with the plates of the gates are of sizes to fit snugly in the casings 16, but allow of free adjustments upwardly and downwardly in the casings. Connected to the bars 57 and 58 of each gate is a rod 59 having a threaded upper portion which is screwed through the threaded aperture of the cap '17 of its re spective casing, and these rods are of lengths so as to extend considerable distances above the casings. On the upper end of the rod 59 of each gate may be a handle, as 60, to

allow the rods to be manually revolved. Through the lower part of the wall of the casing 16 of each of the cylinders is a passage 61 which provides communication between the interior of the casing and the chamber of the body portion 14 of-the cylinder, andleading from the interior of the chamber of the body portion of each cylinder is a waste pipe 62 toallow such water as may flow into the cylinders through their open ends to be exhausted therethrough. When it is desired to repair, or repack one, or both of the plungers 21 and 22 they are moved in the cylinders interiorly of the hull of the boat the required distances, and water is prevented from flowing through the bores of the cylinders by closing the gates 54L and 55. These gates are operated by rotating the rod 59 of each gate for guiding the plate 56 downwardly in its casing sufiicient distance to close the passage through the bore of the cylinder of the gate. The water then admitted through the open end of the cylinder of the gate will flow into the casing of the gate through the passage 61 and through the exhaust pipe 62. When the gates are reversely operated the plungers may be reciprocated, as above described, for propelling the boat.

In the foregoing description, I have embodied the preferred form of my invention, but I do not wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein without departing from the principle, or sacrificing any of the advantages of this invention, therefore I reserve to myself the right to make such changes as fairly fall within the scope thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a ship propelling mechanism, a cylinder with an open end adapted to be arranged in the hull of a ship so that its open end leads exteriorly of the stern of the hull, said cylinder including a tube and a tubular head with a chambered body portion therebetween, a plunger reciprocable in the cylinder inwardly and outwardly of its open end, a roller support for the plunger arranged in the chamber of the cylinder body portion, and means to reciprocate the plunger.
